Resin fibers for treatment of oil bearing waste water and method of treating oil bearing waste water

摘要

A resin fiber to be used for treatment of oil bearing waste water, wherein the resin fiber has a molecular structure having a characteristic group which is positively charged when exposed to oil bearing waste water, or wherein the resin fiber is made of a polymer polymerized with monomers having a characteristic group which is positively charged when exposed to oil bearing waste water, or wherein the resin fiber is made of a copolymer polymerized with acrylonitrile and monomers having a characteristic group which is positively charged when exposed to oil bearing waste water. It is preferable that a compositional ratio of the monomers having the characteristic group is in the range of 5-30%. <IMAGE>
